IMPROVEMENT IN SHADES FOR GAS-BURNERS.

Specification forming part of Letters Patent No. 177,921, dated May 30, 1876; application filed May 5, 1876.

To all whom it may concern:

Be it known that I, WILLIAM F. BONNELL, Jr., of Boston, in the county of Suffolk and State of Massachusetts, have invented an Improvement in Shades, of which'the following is a specification:

may be of other metal or of paper, or other material of which shades are made, and it is adapted to be readily turned about the usual gas flame or globe, and be interposed between the light and a person from whose eyes it is desired to keep the strong light, and so also the strong light may be reflected away from and be lessened at certain desired portions of an apartment. Figure 1 represents a portion of a gas-fixture, which may be of any usual form, this improved shade and holder being shown in position at the right-hand side of the globe and burner, and in such figure the dotted lines outside the globe represent the shade turned directly in front of the globe. Fig. 2 represents the shade and shade-holder detached; Fig. 3, a side and top view of the shade-holder5 Fig. 4, a side and top view of the base, over which the holder is fitted; and

Figs. 5 and 6 representin two positions the shade applied to an Argand burner or ortable stand light.

The portion a of the gas-fixture, provided as usual with a key, b, has at top a screwthreaded portion to receive the internally screw-threaded portion of the base 0, provided at top with an external screw-thread, d, to which the burnershell e isscrewed, the lat ter being of anydesired form or kind. The plate f of the globe-holder 9, adapted to support the globe h, is held between the flange 2 on the base 0 and the shoulder at the junction of the shell and base. The outer portion of the base 0 is made cylindrical, or it may be conical, and is adapted to receive about it the hub 1 of the shade-holder 4, provided at its outer end with a socket to receive the end of a rod, j, attached to and projecting from the shade k, the shade-holder thereby supporting the shade. The lower portion of the holdercollar rests against the flange of the base 0.

It is obvious that the outer end of the shade might be provided with a projection, to enter a socket or hole in the rod j, and the shade is may be of any usual or desired shape; but theshape'shown is preferred, and it may be placed more or less high with relation to the light and globe, according to the height of the light and its distance from the spot from which it is desired to reflect the strong light, and for this purpose the rod may be more or less bent or it may be adjustably attached to the shade, instead of being soldered thereto, as shown in Fig. 2.

Instead of having the rod j as long as shown in the drawing, it might be made much shorter, and the shade-holder be made longer, and the latter might be long enough to connect directly with the shade; but this would not be so desirable as to use the rod 011' the length shown, for the rod j, being usually of wire, may be easily bent when the shade is being applied to a fixture or drop-light, so as to place the shade at the desired angle or po-. sitionvertically with relation to the light;

and from the construction described it will be obvious that the shade and holder may be revolved or turned freely about the globe or light.

The burner herein shown forms the subject-matter of another application filed concurrently with this, and to which reference is holder, and dapte to tfirn frool; y"abo 1t'the 1n tosbimony whereof I have sigud my globe and globe-holder, substantially as denailie to this specificationin-the presence of scribed. 7 two subscribing Witnesses.
